Non custodian parent refusing to give address

If you have proof that you have made several efforts to get in touch with him, then you should have nothing to worry about.  This will prevent him from being able to lie to the court and say that you denied him visitation.  If he is alive but continues to stay out of the picture for another six months or so, then you may have grounds to modify custody. Whether this would be worth the effort depends on the frequency of his visitation rights under the current child custody order.  For instance, if his visitation is not on a set schedule, but rather simply from time to time as you both may agree, then it would make no sense to go back to court because he already has the minimum.  If, on the other hand, he is entitle to every other weekend plus a day or two during the week, then you would be within your rights to claim that his absence is a material change in circumstances justifying even less visitation.  Along these lines, if he is out of the picture due to a drug addiction, or something else that could potentially pose a threat to your child if the father were to exercise visitation rights, then you may want to seek to modify the visitation so that it is supervised. In sum, if he does not already have the minimum (reasonable visitation from time to time as agreed), or if he has done something that would raise a red flag as to your child's health, safety and well-being, then you may want to discuss the matter further with a Maryland Child Custody Lawyer.
