Bitten by dogs in the state of other … which is set to hire a lawyer?
My boyfriend was bitten in the face by a dog of a friend in another state, resulting in emergency plastic surgery and permanent scarring of her mouth area and wants to hire a lawyer to deal with an offer insurance settlement from the other person as proprietor. Can you hire a personal injury attorney in which we live (in Arizona), or is it better to find a lawyer to distance in the state where the bite occurred, as are probably most familiar with the laws of dog bite? (Washington State)?
You would do far better to hire from within the state because he thought it would be more familiar with the laws, but also because you may have to go to the court and then have to sue the state did.
