it depends. do your research on both. normally an agency does the advertising for you, and has a higher amount of birthmothers. an attorney only has the birthmothers that are referred to them by word of mouth. you will be left to do you own advertising, and will have to figure out what questions to ask as to wether or not the birthmother is serious about her adoption plan. an agency is more expensive, but once you figure in the advertising cost, and the prescreening and help they can provide for the birthmother it's well worth it in my opinion. depending on your wants for a child, the wait with the attorney tends to be longer than an agency. what state are you located in? i know a great adoption attorney, whose wife is a social worker and they run an agency in kansas. they seem to have many situations. they were referred to me by the agency that my birthmother was listed with. so i did end up paying the agency fee, as well as the attorney fee. but my wait time was less than 48 hours for a match and our daughter was born a month later. my friend gave their info to my agency and also was matched within 48 hours. and their daughter is due to be born in march. this agency has birthmothers in many states, and requires no fees until a match is made. they prescreen and require proof of pregnancy for the birthmother. their average wait time for a match for a caucasion baby is 6 months. they require no fees be paid until a match is made and if the birthmother should decide to parent, all of your fees roll over into the next match. and even if you do go through an agency, you should have your own personal attorney. by just going with an attorney you are eleminating the agency and fees with them, but you become the agency and have to accept the responsibility of advertising and screening prospective birthparents. personally i think this can be dangerous for you, and the wait and stress will be less if you have an agency involved. either way i hope you find your child and bring them home soon. good luck.
