Changing the child custody and place of living

[anasuya]

My girlfriend(Finnish) has the full custody of child and when the child is living with her.we are unmarried. Is it possible to change the full custody to joint custody in future somehow and is it possible that i can take the child to stay with me?

First you have to be recognized as the father of the child. Then your GF has to agree on joint custody.
If she's reluctant there is little you can do as an unmarried father. She might even claim the child is not yours.
So it is a slow process of trust and good relations.
