Concept:
The Doctrine of Lis Pendens is contained in Section 52 of the Transfer of Property Act, 1882. It means:
Pending litigation
It prevents transfer of immovable property during the pendency of a suit.
• Protects rights of both parties.
• Prevents unfair transfer during litigation.
• Ensures court judgment remains effective.
Step 1: Understand the meaning of Lis Pendens.
The term comes from Latin:
\[
\text{Lis} = Suit,\quad \text{Pendens} = Pending
\]
So:
Lis Pendens = Pending Suit
Step 2: Apply the concept to property transfer.
If property is under dispute:
It cannot be legally transferred to defeat the case
until the court gives judgment.
Step 3: Eliminate other doctrines.
• Subrogation -- substitution of rights
• Acceleration -- speeding up vested interest
• Lis Pendens -- correct
• Estoppel -- prevents denial of earlier statement
Step 4: Final conclusion.
Hence, the correct answer is:
\[
\boxed{\text{Doctrine of Lis Pendens}}
\]
