If you going to get your accounts audited you need to first maintain proper accounts and if you are preparing proper accounts then this question should not arise now.
Anyways first of all you only need to show business assets in this balance sheet.
Second if you say all your assets have been received from your father then also you need to show them properly in your books because if you sell them one day then you need to have some proof that you owned them.
As far as land is concerned it needs to be shown at the value purchased.
As far as depreciable asset is concerned say for eg: building and such things then within 20 years it's wdv would have been zero so just show them in your capital account with negligible value. If there are any asset of which bill is available with you then find it's wdv for 1-4-18 and then calculate depreciation on them because you must be requiring asset to run your business.
Your CA should be knowing all this.
If you don't have a CA we can help you with those services.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
