Hello, please advise. The son of 17 years (in March 18) was still with his ex-wife and came to see me at least once every 14 days. But we saw each other more often. I paid alimony CZK 2,500 + all payments related to school and rings I paid half. I pay my son a phone and an insurance policy. Clothes, etc. I take it for granted and buy a son as needed. Now (since January 3, 2020) my son has passed into my care and lives permanently with me. My ex-wife stopped paying all my obligations, more precisely school lunches, but she also told me that she would not contribute to my son. In court, the son is the decision of the wife and legally it is given what who pays. How should I proceed to contribute at least a sum to my son? Thank you and have a nice day Radomír Čermák
