A more thorough explanation:

lis

A lis is a legal disagreement or argument between two parties.

• John and Jane are in a lis over who owns the property.
• The company is involved in a lis with its former employee over a breach of contract.

These examples show how a lis is a legal dispute or controversy between two parties. In the first example, John and Jane are in a disagreement over who has the legal right to own a property. In the second example, the company and its former employee are in a legal argument over a breach of contract. Both examples illustrate how a lis can arise from a legal disagreement or dispute.
