sir, i met with an accident in 2005 but till date we did not get full amount for the case. i lost one of my leg and the other leg was fractured.

In Indiana, the statute of limitations to sue someone for an injury is 2 years from the date of the accident.  If you do not file a lawsuit within 2 years, your claim will be barred and you will not be able to recover any money for your injuries.  There are some very limited exceptions to this, for example, if you were under age 18 at the time of the accident, the statute of limitations will be tolled until 2 years after your 18th birthday.  If you have specific questions about your case, you should contact an experienced personal injury attorney.
