What are your rights as a stepmother?

Questioner

I recently married the father of three children (under 10 years old). The father has acknowledged the children but has no parental authority. I am a weekend stepmother to the children (they are with us every two weeks and half of the holidays). My husband now pays the mutually agreed maintenance, but I am now wondering (since I am now married to him) whether I should also contribute to the maintenance. The mother of the children (she alone has parental authority and the children live with her) is now sending a lawyer to our house to have the maintenance recalculated and I actually have no idea what my rights and obligations are for this. Of course, the most important thing is that I would like to do my bit, do my best for the children and am also open to the above, but I would like to know what my rights are or are not. I have been told that you are not obliged to do this as a weekend stepmother, but is that also the case in my situation? (incidentally, I am married in community of property, perhaps useful to know)

Lawyer

The criterion is that the children belong to the family, in general this is not assumed in a situation where the children have their main residence with the other parent. There may be a discussion about the ability of your partner to pay if his expenses are actually lower due to the marriage.
