" "og:title": "Marriage & Cohabitation Agreements" description: "We resolve prenuptial, postnuptial, and cohabitation contract disputes—enforcing or challenging terms when relationships end. " --- #### *Our Services* ### Marriage & Cohabitation Agreement Lawyers in Montreal We provide independent legal counsel for individuals negotiating, reviewing, or contesting marriage contracts, civil union contracts, or cohabitation agreements. If you need a proposed agreement reviewed, unfair clauses challenged, or your rights protected as a de facto spouse, we act only for you. We never represent both parties on the same agreement, so our advice stays fully independent and we remain available if a dispute arises later. ### An agreement matters twice: when you sign it and when you need it. We're here for both. [**Book a Consultation**](https://goldwaterdroit.com/en/our-team) ### Who We Represent ##### Professionals & Business Owners Protecting your professional practice, investment portfolio, and business interests through strategic negotiation and careful review of proposed agreements. ##### Individuals Presented with Agreements Reviewing contracts your partner's lawyer or notary has drafted, identifying unfair terms, and negotiating modifications that protect your rights and contributions. ##### Second Marriages & Blended Families Ensuring your new agreement properly balances fresh starts with existing obligations to children and former spouses. ##### Common-Law Partners (De Facto Spouses) Securing legal protections where Quebec law provides none, whether you're proposing an agreement or responding to one. ##### Those Challenging Existing Agreements Attacking contracts obtained through pressure, incomplete disclosure, or lack of proper independent advice, or defending your valid agreement against unfounded challenges. ##### Recipients of Foreign or Religious Contracts Analyzing agreements drafted in other jurisdictions or incorporating religious elements to ensure Quebec law recognition and enforcement. ### Legal Context in Quebec Marriage and cohabitation agreements in Quebec are governed by the Civil Code of Québec. A marriage contract must be executed before a notary and allows couples to choose their matrimonial regime—such as partnership of acquests or separation of property—and exclude assets from the family patrimony. De facto spouses (common-law partners) are not subject to the family patrimony or support obligations unless they enter into a valid cohabitation agreement. Quebec law provides no default protections for unmarried couples, making formal agreements essential. These contracts can also outline future obligations related to separation, death, or financial support. Agreements may be enforced or contested in court depending on the circumstances, particularly in cases involving ambiguity, coercion, or improper disclosure. ### Our Services #### Independent Review of Prenuptial Agreements - Asset exclusion analysis - Regime selection advice - Hidden disadvantage identification - Negotiating protective amendments - Financial disclosure verification - Alternative proposal drafting #### Cohabitation Agreement Advice - Property rights analysis - Support obligation implications - Contribution recognition - Enrichment claim prevention - Separation term negotiation - Estate planning coordination #### Agreement Enforcement & Challenges - Enforcement proceedings - Validity challenges - Duress and coercion claims - Disclosure violations - Ambiguity interpretation - Homologation applications #### Religious & Cultural Contract Analysis - Religious contract interpretation - Civil law integration - Enforceability analysis - Cultural obligation review - Protective clause negotiation - Multi-jurisdictional implications ### Our Experience Eric v.

This clarity prevents surprises and ensures your agreement addresses all scenarios. We identify what needs protection, what's negotiable, and what Quebec law requires. #### Full Disclosure & Independent Advice Quebec courts scrutinize domestic contracts carefully. We ensure complete financial disclosure, proper translation if needed, and confirmation of independent legal advice. These steps prevent future validity challenges and protect your agreement's enforceability. #### Future-Focused Provisions Life changes. Good agreements anticipate career changes, children, inheritance, illness, and retirement. We include modification procedures, review triggers, and dispute resolution mechanisms that prevent court battles when circumstances evolve. #### *Book with the right lawyer for your agreement matter* ### Meet the lawyers handling marriage and cohabitation agreement matters Connect with litigators who regularly draft, review, challenge, and defend marriage contracts and cohabitation agreements across Quebec.
