As the grandmother you have an important role in the child's life, particularly if the child's father has passed away. You don't have an automatic right to have contact, the way a parent does, but nonetheless you can apply to the Family Court if the mother is being difficult. However most people try family mediation first, which is a much faster and less stressful option. I suggest when things have settled down with the new child, if you're having trouble getting contact, then you could start by suggesting to the mother that you have family mediation rather than go to court, but point out that it is an option, and probably more important since the father is not there anymore

Normally one of the parents would be looking after your son's estate. Even though he may not have left anything in his estate, normally his mother or father would help wind up the estate which includes looking after the ashes. If he had a partner at the time of his death, the partner would normally have some say in what happens to the ashes. In a situation like this, like the visitation issue with your grandchild, family mediation is often the best way to resolve matters. If you have to go to court about the ashes that might be quite expensive in lawyers fees, although it would be possible
