Things immediately changed when you had your second child. Although your husband had been both attentive and generous with his time when you brought your first son home from the hospital, your husband seemed both impatient and frustrated when you brought your second son home. Although you had a caesarean section for both boys, your husband did not seem to honor that procedure and the doctor’s guidelines with baby number two.
As an example, just one week after you were home from the hospital your husband informed you that he thought you should get up and move around when you asked him if he would go make a bottle for the baby. This comment might have gone unnoticed but your aunt, uncle, and cousin were visiting when it happened and you noticed their surprise. When your relatives noticed that your husband was being rather sharp and impatient, you realized that these behaviors were, indeed, out of character.
For the next few months you tried to find ways to make sure that you were doing as much as possible yourself, and asking very little of your husband when he returned from work at the end of the day. Having a new baby in the house, however, was exhausting, especially since your older son had just turned three.
Unfortunately, it soon became apparent why your husband was so impatient and frustrated. By the time the baby was six months old you discovered that your husband had been having an affair. And while the thought of being a single parent was daunting, you knew that your husband’s unfaithfulness was something that you could endure. He had made promises before, but this time you acted in your own best interest and contacted a family law attorney. You knew that you might also have to work with child custody lawyers at some point, but you were hopeful that the family law attorney would be able to help you with the entire process.
Consider some of these facts and figures about the reason that many people find themselves looking for help from divorce attorneys:

• There are 876,000 divorces in the U.S. each year. This translates into a new divorce happening every 36 seconds.
• 30% of failing marriages involve couples who have children under the age of 18, so it is often necessary to work with a family law attorney.
• 41% of first marriages end in divorce.
• 1 million children are involved in divorce proceedings in America every year.

If you have been in a car crash you want to make sure that you contact an accident attorney, so it makes sense that if you are facing marital problems you may want to work with a family law attorney.
