If your wife's family is out to get you, and you decide you need a family lawyer to represent your interests, it is probably best if you take a shower and perhaps lay off the moonshine that morning before approaching some random stranger on the street and asking them to recommend an attorney.
On the other side of this equation, it is always a good idea to keep handy the address of the nearest family lawyer, just in case some disreputable looking individual sidles up to you as you're crossing the street and asks you for one. If you are able to quickly provide an address—down two blocks on your right, you can't miss it—you will be able to avoid going into any detail on why or how the individual's wife's family is out to get him, although you can probably come up with a few good reasons yourself, and you are already thinking that you will be siding with them if this ever goes to court and you are called as a witness.
Keep in mind that Coachean Life Coaching handles real-life situations only. Maybe I just look like someone who happens to know the nearest family lawyer, but if I look like that, so do you, and you'd better be prepared. The nearest family lawyer I am aware of is, indeed, down two blocks on the right. They claim to speak Spanish, and they post their prices in the window for divorces, separations and wills, among other various familial legal needs.
And, by the way, they charge two dollars for notarization. And they look very disappointed when you tell them that's all you want. "You're sure you don't want to get divorced?" they ask as they take your two dollars. Divorces cost $500. I felt good saving both $498 and my marriage at the same time. I assume that they handled my new friend on the street quite adequately, as I haven't seen him since. Then again, I have taken to not walking in that particular neighborhood anymore. You can never be too cautious.
