Full and frank financial disclosure by both parties.
Independent legal advice, genuinely received rather than waived.
Time to consider it, well before a wedding date.
Terms that were not unconscionable when made.
Quick Answer
Can a marriage contract protect my business in Ontario?
Yes. Part IV of the Family Law Act allows spouses and people intending to marry to agree in advance on how property will be divided and on spousal support, and a domestic contract can address shares in a company, a professional practice or inherited wealth. To be enforceable it must be in writing, signed and witnessed, made with full financial disclosure, and entered into voluntarily with an understanding of its effect. A court may set aside a contract where disclosure was not given or a party did not understand what they were signing.

WHY OWNERS NEED ONE
The Default Rules Were Not Written for a Company
Without an agreement, Ontario default rules apply. Growth in the value of a business during the marriage enters net family property and is equalised. That is often a fair outcome, and for many families it is exactly the right one. It is a poor outcome where a business has other shareholders who did not marry your spouse, or where the value that grew was built before the relationship began.
The practical risk is not that a spouse takes the company. It is that an equalisation payment must be funded, and funding it can require refinancing, selling assets, or bringing in outside capital on unfavourable terms. A business that is worth a great deal on paper and holds little cash can be seriously damaged by an obligation it cannot readily meet.
That is why shareholder agreements increasingly require every shareholder to have a domestic contract in place. It is not distrust of any individual marriage. It is protection for the other shareholders and for the business, in the same way that a shotgun clause or an insurance requirement is.
WHAT IT CAN DO
Terms That Actually Change the Outcome
A contract can exclude specified property, most usefully shares in a defined company and anything traceable to them, from net family property. It can fix an agreed method or date for valuing an interest, removing the largest single source of dispute. It can address the matrimonial home, which has special treatment under the Act and defeats many otherwise sound plans.
It can also deal with spousal support, by agreeing an amount, a formula, a duration, or a release. Support terms are more vulnerable to later challenge than property terms, particularly where circumstances change substantially, but a well drafted and fairly negotiated support provision carries real weight.
What it cannot do is bind a child. Terms purporting to limit child support or to fix parenting arrangements in advance are not enforceable against the interests of a child, and a contract that overreaches in this way invites scrutiny of everything else in it.
MAKING IT HOLD
Disclosure, Advice and Time
A domestic contract must be in writing, signed and witnessed. Beyond that, the requirements that decide enforceability are practical. Both parties must give full and frank disclosure of significant assets, debts and income. Both must receive independent legal advice. Both must understand what they are agreeing and enter it voluntarily.
Disclosure is where contracts most often fail. An owner who describes a company vaguely, or who values it optimistically low, hands their spouse a ground to set the agreement aside years later, at exactly the moment it is needed. Complete disclosure feels uncomfortable and it is the price of an agreement that works.
Timing is the second failure. An agreement produced days before a wedding, when invitations have gone out and family have travelled, is exposed to an argument about pressure. Start months ahead. An agreement signed calmly, after real negotiation and genuine advice, is a substantially stronger document than one signed under a deadline.
REVIEW
A Contract Written for a Life You No Longer Live
Circumstances change. A contract drafted when a business was small may operate very differently once it has become the main family asset. The arrival of children, the departure of a spouse from the workforce, a sale, or a move to another country can all make terms that were reasonable at the time look markedly different later.
Domestic contracts can be amended by agreement, and a periodic review is sensible for anyone whose circumstances have moved substantially. A contract that both parties still regard as fair is far more likely to survive a challenge than one that has become lopsided through the passage of time.
Where a relationship is already in difficulty, an agreement negotiated at that point is a separation agreement rather than a marriage contract, and different considerations apply. The best time to do this work is when neither party expects to need it.

Can a marriage contract protect my business in Ontario?
Yes. Part IV of the Family Law Act permits spouses and intended spouses to agree on property division and spousal support, and a contract can exclude shares in a company or a professional practice from net family property. It must be in writing, signed and witnessed, with full disclosure and voluntary agreement.
Do we both need our own lawyers?
Independent legal advice for each party is central to enforceability. One lawyer cannot properly advise both. A contract where one party did not receive genuine independent advice is significantly more vulnerable to being set aside.
What if I do not disclose everything?
Incomplete disclosure is the most common reason domestic contracts are set aside. The Family Law Act permits a court to set aside a contract where a party failed to disclose significant assets, debts or liabilities existing when it was made.
Can we sign it the week before the wedding?
It is possible and it is unwise. A contract signed under time pressure invites an argument about duress and undue influence. Beginning several months ahead produces a considerably stronger agreement.
Can a marriage contract deal with children?
Not in respect of child support or decision making about children in a way that binds a court. Those provisions are not enforceable against a child interests, and including them can attract scrutiny of the rest of the contract.

Initial Assessment
The no-obligation initial assessment is a brief introductory conversation. It does not include a review of your documents and does not constitute legal advice. Lexaltico LLP charges a fee for substantive consultations, including civil litigation, criminal defence and immigration matters; the firm may waive that fee at its discretion. Any fee is disclosed in advance and credited in full toward your account if you retain the firm. Documents are reviewed and advice given only at a paid consultation or once the firm has been retained. No solicitor-client relationship arises, and no duty of confidentiality applies, until confirmed in writing.

Legal Notices
How Lexaltico LLP handles personal information, under PIPEDA and Ontario law.
What we collect
What you give us
When you use a form on this site, email us or telephone us, we collect what you choose to send:
your name, email address, telephone number and a description of the situation. Nothing on this
site requires you to give more than that.
What is collected automatically
We collect non identifying technical information when you browse: IP address, browser type, pages
viewed and time spent. It is used to understand how the site is used and to improve it. It is not
used to identify you.
What we do not collect here
We do not collect sensitive personal information through this website. Detailed personal and legal
information is collected only after a solicitor client relationship exists, through the channels
set up for that purpose.
How we use it
Purpose
What you send is used to reply to you, to run a conflict check, to assess whether the firm can
assist, and, if a retainer follows, to carry out the work.
Marketing
We do not use your personal information for marketing without your express consent, and we
do not sell, rent or trade it. If you consent to receive anything from us, every message
carries a way to stop, as required by Canada’s Anti Spam Legislation.
Sharing and disclosure
Privilege
Information given to us in the course of a legal matter is protected by solicitor client
privilege. We do not disclose privileged information without your consent, except where the law or
a court order requires it.
Service providers
Non privileged contact information may be shared with the providers who help us run the firm and
this website, and with people engaged on your matter such as translators, agents and court
reporters. All of them are under confidentiality obligations.
Processing outside Canada
Information submitted through a form travels through third party services in order to reach us by
email, and may be processed or stored outside Canada, where it can be subject to
the laws of that place. Submitting a form is your consent to that transfer. If you would rather
not, telephone us instead.
Cookies and measurement
What is set, and when
This site uses cookies to understand how it is used. Advertising cookies are set only if you press
Accept. If you press Decline, measurement is switched off for you entirely, nothing further
is sent, and anything already stored on your device is cleared. The site works either
way.
You can change your answer at any time by clearing this site’s cookies in your browser, which
brings the question back.
Your rights, and how long we keep things
Your rights under PIPEDA
Under the Personal Information Protection and Electronic Documents Act,
S.C. 2000, c. 5 you may ask what personal information we hold about you, ask us to correct
anything inaccurate, and withdraw consent to our use of it, subject to legal and contractual
limits. We reply within thirty days or explain why we need longer.
Retention
Client files are kept for the period the law and the Law Society require, ordinarily
seven years after a matter closes, which reflects limitation periods and the
possibility of later proceedings. After that they are securely destroyed or anonymised. You may
ask for earlier deletion, subject to those obligations.
Enquiries that do not become files
If you contact us and no retainer follows, what you sent is retained only as long as our conflict
records require, then destroyed.
If you are not satisfied with our answer you may complain to the Office of the Privacy
Commissioner of Canada.
Short, and written to be read rather than scrolled past.
The four things that matter most
Nothing on this site is legal advice, however specific it looks.
Using the site or sending a form does not make us your lawyers.
Do not send confidential information before a retainer is signed.
Past results depend on their own facts and do not predict yours.
What this site is
Information, not advice
This site publishes several hundred pages about Ontario law. They are written carefully, they cite
statutes and cases by name, and they are reviewed. None of that makes them advice about your
matter. Law is applied to facts, and we do not know yours.
The difference is practical rather than technical. A page explaining that spousal support is
usually indefinite after a twenty year marriage is accurate as a general statement and may be
wrong about you, because of a domestic contract you signed, a period of separation you have
forgotten, or an income that is not what a tax return says it is.
Law also changes. Pages carry a review date where one is relevant. A page reviewed last year may
not reflect an amendment made since, and a page about a subject currently before an appellate
court may be overtaken between your reading it and your acting on it.
When we become your lawyers
Three things must happen first
A conflict check must be completed. We act for a great many people and
businesses, and we cannot act against a current client or use what we learned from a former one.
That check happens before anything else and occasionally means we have to decline.
We must confirm in writing that we are prepared to act. Not every matter is one we
can take, and saying so early is better than taking a file we cannot properly serve.
A retainer agreement must be signed. It sets out what we are doing, what we are
not doing, who is responsible for what, and how fees work. Until it is signed no relationship
exists, whatever has been discussed.
Confidentiality before a retainer
Why you should not send us documents yet
Information sent through a form, or by email, before a retainer is signed is not covered by
solicitor client privilege. That is not a policy we chose. It follows from there being no
solicitor client relationship for the privilege to attach to.
It can also create a problem for you. If you send us detailed information about a dispute and we
are later approached by the other side, what you sent may affect whether we can act for either of
you.
So tell us the shape of the problem and leave out the detail: the area of law, roughly when it
arose, and whether anything is urgent. That is enough for us to say whether we can help. The
documents come after the retainer.
Results, testimonials and reviews
What they do and do not tell you
Case results described anywhere on this site are real and are described accurately, and they are
specific to their own facts. A settlement at three times the original offer happened because of
that employer, that contract and that person’s history. It says nothing about what your
matter is worth.
Client reviews are the views of the people who wrote them. We do not offer anything in return for
a review, we do not write them, and we do not ask only the clients we expect to be positive.
Calculators on this site produce estimates from the figures you enter. They apply published
formulas and they cannot know about the facts that most often change the answer.
Copyright, links and governing law
Copyright
The content of this site belongs to Lexaltico LLP or its licensors. You are welcome to read it,
print it and quote it with attribution. You may not republish it as your own.
Links
We link to statutes, regulations, court decisions and government pages because a reader should be
able to check us. We do not control those sites and are not responsible for them, and a link is
not an endorsement.
Limitation of liability
To the fullest extent the law permits, Lexaltico LLP is not liable for any loss arising from your
use of, or reliance on, anything published on this website.
Governing law
These terms are governed by the law of Ontario and the federal law of Canada that applies in
Ontario. Lawyers and licensed professionals at the firm are regulated by the Law Society of
Ontario, and marketing on this site is intended to comply with the
Rules of Professional Conduct.
Every limit on what this website tells you, and every thing it does not do, in one
place rather than in small print at the bottom of each page.
Before you rely on anything here
Four limits, and they matter in this order.
Not legal advice
Everything published on this website is general information. It is not legal
advice, it does not take account of the facts of any particular situation, and reading it does not
create a solicitor client relationship. Do not act, or decide not to act, on anything here without
speaking to a lawyer licensed in your jurisdiction about your own circumstances.
Jurisdiction
These pages describe the law of Ontario, and of Alberta only
where a page says so expressly. They do not describe the law of any other province, territory or
country. Law that looks similar across jurisdictions frequently is not.
Currency of the law
Each page states the law as at the review date shown on it. Legislation is amended and case law
develops. A page accurate when written may no longer be.
Generality
These pages describe how a rule usually works. That is not the same as how it applies to your
facts. The exceptions are where most real matters live, and a page written for a general reader
cannot tell you whether you are inside a rule or inside its exception.
If you contact us
If you are in danger
If you or a child are in immediate danger, call 911.
This website is not an emergency service. Enquiries sent through a form here are read during
business hours and a reply may take up to 2 business days.
Using this website, submitting a form, sending an email or speaking to us on the telephone does
not make us your lawyers. That relationship arises only when the firm has
confirmed in writing that it has agreed to act, a conflict search has been completed, and a
retainer has been signed.
Confidentiality of enquiries
Do not send confidential or sensitive information through this website or by email until we have
confirmed in writing that we can act for you. Information sent before that point is
not treated as confidential and may prevent us from acting for you, or for
someone else, in a connected matter.
Response times
We aim to reply within 2 business days. Contacting us does not guarantee a reply within any
particular period, does not oblige the firm to act, and does not stop, extend or satisfy
any limitation period, filing date or court deadline.
Our telephone line
Our line is answered 24 hours a day, every day of the year. Outside office hours calls are taken
by our intake service, who record your details and pass them to the firm. A lawyer responds during
the next business day, or sooner if the matter is urgent. Answering the telephone is not the same
as giving legal advice, and no relationship arises from that call.
