hi there ... i want to adopt my step children ... i have been married to my husband for 3 years and they have lived with me for that time .... i support them financially ... their birth mother has agreed to sign the adoption papaers if we drop a case for maintanance and we are happy to do so we would rather have the children than the money.... but she wont sign the adoption papers before we sign to stop maintanance .... we are in a catch 22 situation as neither trusts the other not to keep to their part of the agreement ....
