Before 1858 wills were proved by the ecclesiastical courts and it depended on the value and whether your ancestor owned property in more than one ecclestastical district. Leicstershire was in the province of canterbury and formed the archdeaconry of leicester in the diocese of lincoln. So like i say, depending on the likely estate of the testator the will could be a PCC will, (prerogative court of canterbury) in the archdeaconry of leicester or simply in the diocese of lincoln, .If the person did not make a will you can still search for letters of administraion (admons) which would have had to be applied for by the next of kin if the value of the estate was over £5 which would include all possesssions not just property, e.g clothing, furniture, household items and any livestock,
