A separation agreement is a legally binding contract between two spouses (married or common-law) that resolves the issues arising from their separation. It can cover everything: property division, the matrimonial home, spousal support, child support, decision-making responsibility, parenting time, and debt allocation. Once signed by both parties with independent legal advice, it is enforceable in court.
Without a separation agreement, none of your separation issues are legally resolved. That means: either party can return to court at any time to pursue property claims; support obligations remain technically live; parenting arrangements have no binding structure; and if one of you dies, the other's legal rights may be different than expected. Agreements that exist only in emails or handshakes are not enforceable as separation agreements.
Both parties should have their own lawyer review the agreement before signing. This is not a formality — it is what makes the agreement difficult to challenge later. If either party was unrepresented, lacked disclosure, or signed under pressure, the agreement may be set aside by a court. The cost of getting independent legal advice is small compared to the cost of relitigating a poorly drafted agreement.
Separation agreements are not only for married couples. Common-law partners who separate also benefit from a written agreement — particularly around property, which common-law spouses do not divide by the same formula as married spouses. Without a written agreement, common-law partners may have to prove their entitlement through claims like unjust enrichment or constructive trust, which is expensive and uncertain.
There is no legal deadline for entering into a separation agreement, but delay often creates problems. Values change, assets are depleted, parenting patterns become entrenched, and memories of what was agreed become unreliable. The sooner a separation agreement is in place, the more control both parties have over the outcome.
