Jeremy: When two people have been living together and they decide not to live together anymore, they are seperatedWhen two people stop living together.
When married parents separate, their marriageA legal agreement that allows two people to live together in a legal union. is not yet ended. Married people need to get divorce to end a marriage.
Parents who separate often make a separation agreementA paper that two people sign when they have separated, that says where their kids will live and how they will divide the things they own that says who their kids are going to live with and how they are going to split up the things they own. This is a paper that they both sign.
A separation agreement is not the same as a divorce, but it is a contract, which means both parents have to do what they agreed to do.
