Hello,
These type of cases abound nowadays wherein wives take money and then back off from a mutual divorce citing reasons such as insufficient money, pressure from the husband,etc. and then again contest the case in the family court. The money should NOT be given beforehand under any circumstances. If she is after the money and is trying to dupe you..She will demand money before the decree which she is doing. Here you are the losing party. Therefore tell them that a bank draft can be given on the day the court passes the decree and an agreement should be signed that in case of the wife backing off she will not receive the money.
These conditions have to be imposed so that your interests are safeguarded.
Regards
