I want to withdraw counts of alimony spousal support, alimony pendente lite counsel fees and costs, child custody, child support and equitable distribution and property rights
You should be able to file an amended motion to the court/ an amended complaint, however I strongly suggest you chat with a local PA attny before giving up all of those rights. Take care and good luck.
You need an agreement signed by both parties to withdraw all the counts and then you need to put a Praecipe sheet on top of the agreement asking the Court to withdraw all counts based on the attached agreement. It is simply a caption with the name Praecipe underneath and then a request to withdraw based on attached Exhibit "A" which is your agreement. You will also need an order sheet for the Judge to sign to withdraw all the counts.
