Do both spouses need their own lawyers for an uncontested divorce in Ontario?

No, there is no legal requirement for both spouses to retain separate lawyers in an uncontested divorce. Many couples complete a straightforward uncontested divorce with only one lawyer involved, or with neither spouse using a lawyer at all.

However, a lawyer cannot represent both spouses simultaneously because of the potential conflict of interest. If only one spouse hires a lawyer, that lawyer represents only that client and cannot advise the other spouse. This can create a power imbalance if one spouse is less informed about their legal rights.

If a separation agreement is part of the process, independent legal advice (ILA) — each spouse consulting their own lawyer separately before signing — is strongly recommended and sometimes required by the agreement itself to make it difficult to challenge later. A spouse who did not receive ILA may later argue they signed under pressure or without understanding the terms.

For a truly simple uncontested divorce with no children, no property, and no support, self-representation or using one lawyer for the filing steps can work. But wherever there is a financial agreement or children involved, both parties getting at least a consultation with their own lawyer is wise protection.
