Book My 15-Minute Assessment →International Custody Disputes | Hague Convention on Child Abduction | Jurisdiction Determination | Foreign Orders
The Hague Convention on the Civil Aspects of International Child Abduction (1980) is an international treaty that provides for the prompt return of children wrongfully removed from or retained outside their country of habitual residence. Canada is a signatory, and the Convention is implemented in Ontario through section 46 of the Children's Law Reform Act.

International custody disputes arise when parents reside in different countries, when a parent relocates abroad with a child, or when foreign custody orders need to be enforced or challenged in Ontario. These cases engage a complex interplay of Ontario statutory law under the Children's Law Reform Act, R.S.O. 1990, c. C.12, the federal Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), and international instruments including the Hague Convention on the Civil Aspects of International Child Abduction (1980). The jurisdictional analysis alone can determine the outcome of the case.
Lexaltico LLP has handled international custody matters involving over 30 countries across North America, Europe, the Middle East, and Asia. We understand the procedural and substantive differences between legal systems and how those differences affect custody outcomes. Our lawyers work with foreign counsel, consular offices, and international family law organizations to coordinate strategy across jurisdictions. When a child has been wrongfully removed to or retained in Ontario, or when an Ontario child has been taken abroad, we act swiftly to invoke the appropriate legal mechanisms.
The Hague Convention on the Civil Aspects of International Child Abduction, implemented in Canada through the federal Civil Aspects of International Child Abduction Act and in Ontario through section 46 of the Children's Law Reform Act, provides a mechanism for the prompt return of children who have been wrongfully removed from or retained outside their country of habitual residence. The central concept is habitual residence: the Convention mandates the return of the child to the country of habitual residence so that the courts of that country can determine custody on the merits. The Supreme Court of Canada in Office of the Children's Lawyer v. Balev, 2018 SCC 16, adopted a hybrid approach to determining habitual residence, considering both the parents' shared intention and the child's connections to a jurisdiction.
Defences to a Hague Convention return application include the Article 13(b) defence (grave risk of harm to the child upon return), the child's objection where the child has attained a sufficient age and maturity, consent or acquiescence by the left-behind parent, and the passage of more than one year since the wrongful removal or retention where the child has become settled in the new environment. Under section 22 of the CLRA, Ontario courts also have jurisdiction based on the child's habitual residence in Ontario, or the child's presence in Ontario combined with substantial connection. Lexaltico LLP has argued both Hague Convention applications and defences, and we understand the nuances of this highly specialized area of family law.
Under section 41 of the Children's Law Reform Act, an Ontario court may recognize and enforce an extraprovincial custody order, including orders from foreign jurisdictions, where the order was made by a court that had jurisdiction based on the child's habitual residence or substantial connection. The court considers factors including the best interests of the child, the circumstances under which the foreign order was made, and whether the parties had adequate notice and opportunity to be heard in the foreign proceedings. Ontario courts will generally give effect to foreign custody orders unless enforcement would be contrary to the best interests of the child or would contravene public policy.
Lexaltico LLP assists clients in registering and enforcing foreign custody orders in Ontario and in challenging the recognition of foreign orders that were made without proper jurisdiction, adequate notice, or due process. We also assist Ontario parents in enforcing Ontario custody orders abroad, working with foreign counsel to navigate the enforcement mechanisms available in the destination jurisdiction. International custody litigation requires a strategic approach that accounts for the legal systems, cultural norms, and practical realities of multiple countries. Our firm provides the sophisticated advocacy these cases demand, supported by a global network of trusted family law practitioners.

How Lexaltico LLP handles personal information, under PIPEDA and Ontario law.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
If you contact us and no retainer follows, what you sent is retained only as long as our conflict records require, then destroyed.

Short, and written to be read rather than scrolled past.
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.
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.
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.
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.

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.
Four limits, and they matter in this order.
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.
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.
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.
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 or a child are in immediate danger, call 911.

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.
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.
We aim to reply within one business day. 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 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.
Lexaltico LLP is regulated by the Law Society of Ontario under the Law Society Act, R.S.O. 1990, c. L.8. All lawyers practising in Ontario through the firm are members in good standing.
Alberta matters are handled by lawyers licensed with, and in good standing with, the Law Society of Alberta. A lawyer licensed in Ontario is not thereby licensed in Alberta, and the reverse is also true.
Immigration consulting is provided by Regulated Canadian Immigration Consultants in good standing with the College of Immigration and Citizenship Consultants under the College of Immigration and Citizenship Consultants Act, S.C. 2019, c. 29, s. 292.
Not everyone at the firm is a lawyer.
Each page and biography states which applies. Ask at the outset who will handle your matter and under which licence.
We serve clients in thirteen languages. Every page of this website is written and published in English. Where anything is provided in another language, the English version governs in the event of a difference. If you need an interpreter, tell us when you book and we will arrange one.
The complimentary 15 minute initial assessment is a brief introductory conversation. It does not include a review of your documents and does not constitute legal advice.
The firm charges a fee for substantive consultations, including in 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.
Where we refer a matter to another firm, including through LexKonnect, we comply with Rule 3.6-6.1 of the Law Society of Ontario’s Rules of Professional Conduct. Any referral fee is set out in the Law Society’s standard referral agreement, signed by you before the referral proceeds, and no fee is payable to us unless and until the receiving firm has been paid for its work. You are never obliged to accept a referral and are free to retain any firm you choose. No referral arrangement affects the independent professional judgment of any lawyer at this firm.
They produce estimates from what you type and cannot know the rest. They do not account for the terms of your contract, statutory exceptions, or the discretion a court will apply. Do not make a decision on a number produced by a calculator.
Any outcome described happened on its own facts, before its own decision maker, under the law as it stood at the time. Past results do not predict or guarantee the result of any other case.
Reviews shown here are written by third parties and published on platforms we do not control. Each describes one person’s experience of one matter. They are not a promise, a prediction or a guarantee about any other matter.
This site links to regulators, courts, government sources, professional associations and social platforms, all operated by others. We do not control them, we are not responsible for their content or accuracy, and a link is not an endorsement.
Failure to start a proceeding within the applicable limitation period may permanently bar your claim. In Ontario the general period is two years from discovery under the Limitations Act, 2002, S.O. 2002, c. 24, Sched. B. Shorter periods apply to many claims. Seek advice promptly. Nothing on this website extends a limitation period.
