#### *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.

### 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

Protect your interests before signing. When presented with a marriage contract, we provide thorough independent legal advice, analyzing every clause for fairness and hidden risks. We negotiate modifications to protect your assets, clarify your obligations, and ensure you understand exactly what you're agreeing to before the notary appointment.

- Asset exclusion analysis
- Regime selection advice
- Hidden disadvantage identification
- Negotiating protective amendments
- Financial disclosure verification
- Alternative proposal drafting

#### Cohabitation Agreement Advice

Quebec law offers common-law couples few protections for property, support, or succession rights. A cohabitation agreement fills this void. Whether your partner has proposed terms through their lawyer or you're starting from scratch, we ensure you understand what you're agreeing to and help you anticipate different scenarios so your agreement protects you no matter how your relationship evolves. This isn't just paperwork—it's clarity, fairness, and peace of mind.

- Property rights analysis
- Support obligation implications
- Contribution recognition
- Enrichment claim prevention
- Separation term negotiation
- Estate planning coordination

#### Agreement Enforcement & Challenges

When contracts fail or were never fair. We litigate to enforce your valid agreement when your ex-partner breaches it, or challenge their agreement when it was obtained improperly. Our courtroom experience includes setting aside contracts for non-disclosure, duress, or lack of independent legal advice.

- Enforcement proceedings
- Validity challenges
- Duress and coercion claims
- Disclosure violations
- Ambiguity interpretation
- Homologation applications

#### Religious & Cultural Contract Analysis

Understanding dual obligations. We review religious marriage contracts (ketubah, nikah, mahr) to explain their interaction with Quebec civil law. When your spouse's family presents religious agreements, we ensure you understand both the religious and civil implications before signing, and negotiate protections where possible.

- Religious contract interpretation
- Civil law integration
- Enforceability analysis
- Cultural obligation review
- Protective clause negotiation
- Multi-jurisdictional implications

### Our Approach

#### Initial Financial Mapping

Before drafting anything, we map your complete financial picture: assets, debts, businesses, inheritance expectations, and future plans. 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.
