Maryland Divorce ~ Voluntary Separation and No-Fault Divorce in Maryland
The state of Maryland has a "no-fault" divorce known also as voluntary separation. This means you and your spouse have separated after mutually and voluntarily agreeing that you no longer wish to live together as husband and wife and there is no hope for reconciliation. To get a divorce on this ground you must be separated without interruption, without cohabitation for one year.
If this is not a mutual and voluntary situation you will have to use other grounds for divorce.
There are two types of voluntary separation : one for limited divorce and one for absolute divorce. An important fact to remember is that limited divorce is not a complete end to your marriage.
