It depends what court you are in, if you are in District Court, then the maximum you can receive on any individual charge is 2.5 years in the house of correction (this does not mean that you can have sentences served 'from and after' another sentence - i.e. 2.5 years and then another sentence starting in 2.5 years).
It is not clear which charges you think you might be convicted of, so I can't give you a certain answer. If you have an attorney he or she is the one that you need to...
I would not recommend as general rule to plea the first day you go to court on a felony.
If you can't afford a lawyer - the court will appoint one at a minimal fee. Otherwise, you should hire an attorney ASAP.
A felony stays on your record for at least ten years (if you can then seal it), will show up on every time your record is run by an employer or school, and may impact your immigration status if that's applicable.
It's the Commonwealth's burden to prove that you committed this...
If he has not directly threatened your son or put him in danger by hurting your son's mother, it may be tough to get a restraining order. You can try. You can do this in District Court where your son lives OR you can go to Probate Court.
You can also go to Probate Court and file for Modification of your current custody arrangement if you do not want this man around your son. This may be your best bet - go to Probate Court and file both a Modification and a 209A.
To prevent being arrested you should go to court immediately. Could they hold you? Yes. WIll they? It is unlikely unless there is something else going on. You may want to consider hiring a lawyer and bringing him or her with you if you are very nervous.
You can be charged for operating a motor vehicle without a license. This is if you actually have never had a license - if you have a license but it is suspended for some reason or another, depending on the reason you can be looking at a fine or jail time.
There are two ways that the Commonwealth can prove OUI. If your lawyer hasn't gone over this with you, you really need to speak to him or her. The Commonwealth can proceed under the theory that you were 'per se' intoxicated due to a BT of over .08 OR they can just try to prove that you were impaired while driving the motor vehicle without submitted any evidence.
Again, it sounds like you have a lawyer, you should only be discussing your case with him or her.
You need to have a conversation with your attorney regarding your concerns.
Also, you don't hire a lawyer to tell you what you want to hear, you hire a lawyer to represent you based on the information and facts at hand.
Usually, Domestic Violence prosecutors are trained as to the different types of abuse, however, a lot of it cannot be used at trial in most cases as there is often not evidence that is admissible in court. Generally, Domestic Violence Prosecutors are compassionate with victims and do their best.
