How do you words a notice for not responsible for someone debts in a newspaper?

You have absolutely TERRIBLE grammar. You don't "Words" something, you "Word" it. It's someone's debt, and you should have said, "...for not being responsible..."

If your question really is "How do you Word a notice for not being responsible for someone's debt in a newspaper?" then the answer is...

Use a large vocabulary, you will be taken seriously. Tell who you are, who they are, what the debt is, and why you aren't responsible. Then tell them some things you have done to become not responsible for the debt. The end.
