My son's father left the city of Toledo, OH in July 07' He left for a vacation to go to Arizona to help his uncle because he was ill. A month later Aug 07' he came back for about 2 days, packed up all his belongings and his wife and other child's. He told me that day that he was leaving for good. He has not been in contact with my son on a continuous base. The last time that either I or my son has spoke with him was about December 07 or January 08. I was wondering what is considered abdonment? He has paid some child support but not on a regular bases. Please somebody help me.

Unfortunately, what he has done is not considered, by law, abandonment. This is one of the most popular post which I have seen. Possibly reading through the other similar questions and answers will explain this more for you.

Just in case:

Title V
JUDICIAL BRANCH Chapter 39
PROCEEDINGS RELATING TO CHILDREN

39.01 Definitions.--When used in this chapter, unless the context otherwise requires:

(1) "Abandoned" means a situation in which the parent or legal custodian of a child or, in the absence of a parent or legal custodian, the caregiver responsible for the child's welfare, while being able, makes no provision for the child's support and makes no effort to communicate with the child, which situation is sufficient to evince a willful rejection of parental obligations. If the efforts of the parent or legal custodian, or caregiver primarily responsible for the child's welfare, to support and communicate with the child are, in the opinion of the court, only marginal efforts that do not evince a settled purpose to assume all parental duties, the court may declare the child to be abandoned. The term "abandoned" does not include an abandoned newborn infant as described in s. 383.50, a "child in need of services" as defined in chapter 984, or a "family in need of services" as defined in chapter 984. The incarceration of a parent, legal custodian, or caregiver responsible for a child's welfare may support a finding of abandonment.

No, this is considered by a lousy father. And for some it is merely moving away for business and being a lousy father.

But you just take him back to court for the child support, try and get a garnishment of his pay, makes it a lot easier. If he is behind, see if they will suspend his drivers license or even put him in jail for a week or so, to help remind him to pay his child support.

But not sure what you were trying to do with abandoment anyway ?
