No. It is important that you both have separate lawyers. Even if you agree on the terms of settlement and have agreed to enter into a separation agreement, you each need your own lawyer to give you independent legal advice. The best way to ensure fairness in the terms of settlement is to ensure each party is fully aware of their respective rights and obligations as set out in the terms of the contract and the nature and consequences of the terms of the contract. If your spouse tries to challenge the contract in the future, a court is more likely to uphold the contract if you have both had independent legal advice and representation before signing and you have both have had meaningful input into the terms of the contract, each with the assistance of their own lawyers.
