Hi everyone, so dd and dp have a solid daughter/ father relationship and we are looking into adoption. We have been together 6 years adoption no he has brought up from a baby. I have no father on the birth certificate but know who the biological father is. Do we still need his permission? How tricky will this be? Thanks. To note: dd knows of bio dad but never seen him nor does he pay any maintenance and me, dp and dd have lived together for 3 years. Thanks in advance xx
