Hi and welcome to JA. I am Ray and will be the expert helping you today.
You would need to make petition for probate
of testament and to be appointed the personal representative.You will have to attend at least one hearing.This is filed in the parish where the deceased resided.
Expect this to take about 6 months to a year from start to finish.Once appointed you gather assets, pay any claims, file final return, distribute property.
Expect a lawyer to charge you from $2,500 to $3,500 ball park.You may want to shop fees and get one that gives you a flat fee.
Here is a good summary of the process..
You can locate a probate lawyer here, there is referral with ratings.
You can also do this yourself called pro se, here are the forms you need to file.
This will save you legal fees here and allow you to do it yourself.
The lawyer would also transfer any property that is not sold to you if you are the legal heir
here under the will.You need to do this to have legal title to any real estate
, cars, personal property,etc.
I appreciate the chance to help you today.Please let me know if you have more follow up.Thanks again.
