Yes,Definitely.
You may prepare a WILL and put the same wording the way you have posted in the present matter.
You need two witnesses to attest your WILL and they should not be a beneficiary and executor of your WILL.
While finalizing WILL Please appoint an Executor of your WILL who should not be beneficiary of your estate.
The WILL is not mandatorily required to be registered with competent authorities, it is optional for your choice for registration.
You may put your own clauses in common parlance and complete the WILL in favor of your parents and wife for their lifetime benefits and interest. No harm using your own words in lucid language which are sound and clear without any ambiguity latent or patent.
