Through negotiation and mediation, the parties can come to a satisfactory arrangement without the need for a protracted court proceeding. A separation agreement in Ottawa will usually cover essential issues, and for the parties involved, especially children, it can mean stability, predictability, and ongoing flexibility.

A negotiated agreement saves time and money for all concerned. In some cases, the separating parties agree between themselves before consulting Ottawa divorce lawyers. In other cases, it requires counseling and mediation to reach an agreement. In any case, both parties need to realize that a solution will only be possible through compromise. Legal counsel will be able to make recommendations about professionals or to help negotiate sticking points.

A valid separation agreement in Ottawa will mean that both parties understand the agreed terms and any consequences that may occur if the agreement is not followed. A separation agreement is a legally binding document that sets out the parties intent and all the items in contention. Because it is a legal agreement, it is always best for the parties to hire family lawyers for representation.

Independent legal advice and the formal requirements

Ontario's Family Law Act sets the formal rules. A separation agreement, and any agreement to amend or cancel one, is unenforceable unless it is made in writing, signed by the parties and witnessed (Family Law Act, s. 55(1)). The Act also covers capacity: a minor can enter a domestic contract subject to court approval (s. 55(2)), and for a mentally incapable person a guardian of property or attorney under a continuing power of attorney for property (who is not the spouse) may do so with the court's prior approval (s. 55(3)); in other cases the Public Guardian and Trustee may act (s. 55(4)).

The Act does not list independent legal advice (ILA) as one of those formalities. It does let a court set aside an agreement, or part of it, if a party did not understand the nature or consequences of the agreement, or if a party failed to disclose significant assets, debts or other liabilities that existed when it was made (s. 56(4)). That is why each side having its own lawyer review the agreement before signing matters: ILA gives each person a record that they were advised on the terms and their effect. Our separation agreement lawyers in Ottawa can review a proposed agreement with you before you sign it.

What a separation agreement can cover (s. 54): ownership or division of property; support obligations; the right to direct the children's education and moral training; decision-making responsibility and parenting time; and any other matter in settling your affairs. A court may disregard a parenting term if that is in the child's best interests (s. 56(1)), and may disregard a child support term that is unreasonable having regard to the child support guidelines (s. 56(1.1)).

Another major issue can be full financial disclosure. A court may set aside a separation agreement, or part of it, if a party failed to disclose significant assets, or significant debts or other liabilities, that existed when the agreement was made (Family Law Act, s. 56(4)(a)). Full disclosure usually involves tax documents, asset statements and a list of liabilities.

Don't let the property deadline pass. If you were married, a claim to equalize net family property can't be brought after the earliest of: two years after a divorce or nullity judgment, six years after you separate with no reasonable prospect of reconciliation, or six months after a spouse's death (Family Law Act, s. 7(3)). A separation agreement that settles property should be signed well inside those limits.

Costs

Going to trial means significant expenses. In addition to the lawyer’s fees, there are also court costs. Because the courts are so overwhelmed, getting a court date can take quite some time. There is also the value of your time.

Operating through a separation agreement involves less lawyer's fees and there are no lengthy wait for a court date or its costs. A signed and witnessed separation agreement is a binding contract, and its support terms can be filed with the court and enforced as if they were a court order (Family Law Act, ss. 35, 55(1)). The only difference is that both parties agree between themselves about the disposition of property, any support payments, and how the children will be affected.

Separation agreement FAQs

Does a separation agreement have to be witnessed?

Yes. It must be in writing, signed by both parties and witnessed to be enforceable (Family Law Act, s. 55(1)).

Is independent legal advice required by law?

The Family Law Act's formal requirements are writing, signatures and a witness (s. 55(1)). A court can set an agreement aside if a party didn't understand its nature or consequences (s. 56(4)(b)), so each party getting their own legal advice is strongly recommended.

Can we change our separation agreement later?

Yes, by a further agreement, and the amendment has to meet the same formalities: in writing, signed and witnessed (s. 55(1)).

Can a court enforce the support terms?

A support provision in a domestic contract can be filed with the Ontario Court of Justice or the Family Court of the Superior Court of Justice and then enforced, and varied, as if it were a court order (s. 35(1)–(2)).
