Sit down with you lawyer to discuss this matter ASAP. If you do not like the answers he/she provides then consult with another attorney ASAP. If you endorse the check and deposit it into your account you may be waiving claims you would wish you hadn't. This matter is time sensitive, so do not delay.
I recommend that you sit down with your lawyer for answers on this issue. Or get the opinion of a local attorney immediately. From what you say here it appears that the court already ordered the matter "settled" if that is the case your options are different than if you need to formalize the settlement
This is too important and time sensitive for you to rely on online advice. You really need to make an appointment with a personal injury attorney to discuss all the facts and circumstances. This is the only way to get competent legal advice.
