Correction in will

Dear Sir,

My mother who is alive had made a will two years back. The will was made through the services of a lawyer.

Now I have noticed that the spelling of my society's name in the will is wrong. Instead of " Patrakar " it is typed as  " Patkar ". Please guide what should I do to get this corrected. Or should I go for a new will altogether.

Thanks in advance,

Prashant
