Hello, I am asking you about my daughter, who will be 9 years old in a few months. I have been caring for my daughter since I was less than 4 years old, when she was in the upbringing of her mother for a year based on a court agreement. She also transferred to my care on the basis of an agreement where the mother was unable to provide a proper upbringing. My mother and I agreed that she would contribute CZK 1,000 to her daughter because she had certain personal problems at the time. At present, however, there is an increasing need for a daughter who stems from older age - school, clubs, but also expenses associated with health care - regular commute to the doctor, purchase of glasses, etc. The mother currently has another maintenance obligation for almost two years child when living in the same household as the child's father in his family house. About a year ago, we agreed that he would contribute CZK 500 more, which she eventually agreed to and fulfilled. He only sees his daughter during the holidays, when he takes her into his household, he refuses extended weekends with the words "that it will not pay off for her". It does not contribute beyond maintenance, although we have agreed on this several times, for example, it will contribute to the purchase of glasses. In the summer, when my daughter was with her for 4 weeks, they planned to go on holiday to the sea - the mother came up with the idea that she would not pay alimony if she had her daughter with her and went with her to the sea - I did not agree, but we agreed that I will contribute to this vacation in a way of reduced alimony. Although the mother did not go on planned leave with her daughter, she sent alimony reduced for both months of the holiday, always by the amount we agreed orally, ie only in the amount stated in the judgment. At present, the mother sends only the amount stated in the judgment, ie in the amount of CZK 1,000, with the proviso that she can no longer do so "for personal reasons" (she will get married). I was considering a proposal to consider alimony or one-off alimony at an increased cost. However, this told me that the mother received only maternity leave and that, on the contrary, maintenance could be reduced because she herself had another maintenance obligation for the other child. That is why I am asking you with my question when I would need advice on whether I have a chance to achieve an increase in maintenance, or whether there is a risk that maintenance would be reduced. The mother lives in the same household as the father of the second child. Thank you for answer. Thomas
