I suggest you think long and hard about this before filing a dissolution of the marriage.
Most courts and experts agree that except in unusual cases it is most important for a child to have a strong relationship with both parents. Thus, courts will typically conclude that an award of custody to the parent who is most likely to foster a relationship between the child and the other parent is in the child's best interests. For this reason, if a custodial parent has demonstrated in the past a pattern of interference with the relationship between the child and the noncustodial parent, unless other facts dictate a different holding, courts will frequently conclude that a substantial change in circumstances justifying a change of custody has occurred.
Not surprisingly, there is a long-standing tradition of awarding a change of custody where the custodial parent has interfered with the parental rights of the other parent. The Court of Appeals of Maryland clearly established this point in Berlin v. Berlin, 239 Md. 52, 210 A.2d 380 (1965). In Berlin, the parties entered into a written separation agreement. Pursuant to the agreement, incorporated into the court's order, custody of the children was awarded to the mother, and the father received reasonable visitation rights. In addition, the parties also agreed that the mother would notify the father if the mother moved out of the Washington metropolitan area. Subsequently, the mother began denying the father his right to visitation. For this reason, the father requested a change in custody. The trial court granted the father's request, and the mother appealed.
On appeal, the Court of Appeals of Maryland held that the trial court properly changed custody to the father. As support for its decision, the court noted only that "the record indicates that the mother had deprived the father of his rights of visitation for a substantial period of time and that he is a fit and proper person to have custody of the children." 210 A.2d at 384. Thus, in Maryland, where a parent has attempted to create emotional distance between the other parent and the child, that parent has committed an act so egregious that the other parent could be awarded custody based solely on this one fact.
You may belive that custody will not be an issue, but once you file for divorce, the rules change and the fact that you left with the child without provision for the father to exercise his legal rights, can and will be a factor in the determination of custody.
