On line wills are as binding as any other will, please make sure they are correctly witnessed, by non-beneficiaries, if they are not the will is still valid but the witness who is also a beneficiary is unable to inherit. Make sure the executors are aware they are executors; many testators name the main beneficiaries as executors, which can be a good idea and ensure the executors know where to find the will. Wills that are badly drawn or not clear can cause endless trouble and expense.
