Is a payment plan unrealistically difficult for a party? Will children be able to adapt to common parenting? Are the obligations of the parties too complex between them? Are they too optimistic? Are they affordable? While it is preferable for all issues between the parties to be dealt with in a separation agreement, the simpler an agreement is, the better it will work normally in real life. Establishing a separation contract requires a great deal of skill and a solid understanding of family and contract law. While kits are available to help you close a deal, I strongly advise you to hire a lawyer who will take care of the matter if the content of your agreement is far from quite simple. Spouses cannot share the same lawyer. To keep lawyers` fees low, a spouse`s lawyer could prepare the arrangement. The other spouse can then consult a lawyer for independent legal advice on the matter.
