Are you thinking about separation?
A married couple may decide to separate or live apart at any time, without authorisation from the court. However, when the couple announces their intent to live apart to a court, then they are seeking a legal separation. Since a legal separation is a judicial procedure, there are issues that must be decided by a judge. For example, issues such as custody of the children, support of the children and the partner, are usually decided in legal separations. Nonetheless, it is important to note that all these things can be reviewed or retracted if the couple seeks a divorce in the future.
