Am soon to be marry and I would like to how can I go about having my soon to be husband to adopt my children without lawyer and where can I find the information am locate in Maryland

If the bio father is in agreement it is not really that hard, and you can get a paralegal or even download the forms from the internet. Now if the bio father is not willing to sign off on this, you will need an attorney

If the biological father will sign over his rights, then it will be easy. However, if he will not then you will need a lawyer.
Find the father, see if he'll sign over his parental rights. You can try to do the papers yourself, but be sure you know how to complete them correctly. Or you can contact a document prep service like the one below, they'll help you complete the docs & make sure you're abiding by Maryland laws.
Good Luck!
