In Pa. if the wife has a child, the husband must support the child until 18 even if it isn't his.
A relative (very close) had a visectomy(sp) when a young man.....he loved running around and wanted no children. After several years of marriage they separated for awhile.
She got pregnant......and after he went to his lawyers was informed that Too Bad....he had to pay support.
All ended well as they got back together and the daughter is the love of his life.
I'll never tell!
Your post illustrates why men should get vasectomies AND refuse to marry. Marriage and children are a free pass for government control of a man's life. Men should do every thing they can to prevent the state from controlling their right to work, live and prosper from the simple act of having sex.
Unless a man wants children, he is crazy to get married, because if his wife wants them, she can have them without him, and STILL make him pay. This applies to step-fathers too in some states.
