Uncontested divorce
An uncontested divorce is preferred because it is quick and simple. For this divorce, parties do not need to have a ground to sever their marriage.  Their mutual agreement to end the marriage is enough.  Both spouses must be present when applying for an uncontested divorce.  It is conducted at the amphur office
Uncontested divorce is usually preferred  by Thais.  But foreigners must take care before proceeding with an uncontested divorce.  because it is not recognized in all countries, and it may pose more problems especially if the foreigner has plans of remarrying
Contested divorce
In a contested divorce one party to the marriage may to go to the courts to end his/her marriage if there is a definite ground for divorce and only one of the parties wishes to end the marriage, if one party has been absent, and the absence has been a detrimental to the other.  or there are disagreements on child custody or marital property which the parties cannot settle by themselves, and the court’s intervention is necessary to put an end to the marriage.
