There are so many reasons why some couples did get through on their marriage. One because they are not happy together and there are more reasons why couples got separated.
I also notice that most of the couples who are dealing with separation or divorce are the people who have money. Which is also involve a family lawyers especially if they have children. The decisions surrounding child custody can be determined without the need of court proceedings if both parties can come to a mutually acceptable agreement.
I know that here in the United States have different rules in every state. And I don’t really know what exactly their rules, but the family lawyers .
