Marriage is not the right choice for everyone, and sometimes an annulment proceeding is best for everyone. The cost of these is always a concern of the parties involved. The average cost of an annulment is $450. The price may range from $200 to as high as $1,000. These costs do not factor in the hiring of a lawyer. Lawyer fees can add another $500 to $2,000 to the above fees. More expensive lawyers or particularly messy divorce proceedings can lead to even higher charges.
