Civil suit for partition

If court has passed orders to take summons then you may have to file a petition under order V rule 20 CPC to serve the summons on them through substituted service, i.e., through a newspaper 

You ask your advocate who knows the procedure and be in regular touch with your advocate  to progress the case accordingly

Selling an ancestral house in India can trigger long-term capital gains (LTCG) tax if the property has been held for more than 24 months. Here's a breakdown of what you need to know: 

 Tax Liability on Sale of Ancestral Property Capital Gain Calculation: Sale Price – Indexed Cost of Acquisition = LTCG Since it's ancestral, the cost of acquisition is usually the value as of April 1, 2001, or the actual purchase price if acquired after that. You can apply indexation to adjust for inflation. Tax Rate: LTCG is taxed at 20% (plus applicable surcharge and cess). 

 Ways to Save LTCG Tax You can claim exemption under the following sections by reinvesting the capital gain: 

 Section 54 Reinvest in a residential property in India within: 1 year before or 2 years after the sale (for purchase) or 3 years (for construction) You must not sell the new property within 3 years. 

 Section 54EC Invest in specified bonds (like NHAI or REC) within 6 months of sale. Maximum investment allowed: ₹50 lakh. Bonds have a lock-in period of 5 years. 

 Section 54F Applies if the entire sale proceeds (not just gains) are invested in a residential house. You must not own more than one residential house on the date of transfer.

This reply is not relevant to my query.

When all defendants (including mother and sister in Delhi) have been served with summons as stated by you, inter alia, that, "Summons served to all through bailiff except one sister in Delhi by RAD in end Jan 2025..... Subsequently you have stated that, "......Now my sister has received the summons but the bailiff report is saying could not deliver."

It is a conflicting statement, which can be clarified by persuing /inspection of judicial file by you / your or some other lawyer.
