We often encounter questions about co-ops and trusts, particularly in the context of New York City real estate. Here's a comprehensive guide to help you navigate these complex topics.
What is a Co-op?
A co-op, short for cooperative housing, is a unique form of property ownership prevalent in New York City. When you purchase a co-op:
You're buying shares in a corporation that owns the building, not the actual apartment.
Instead of a deed, you receive stock certificates and a proprietary lease.
Approximately 70% of buildings in New York City are co-ops.
Key aspects of co-ops include:
Governed by bylaws that define terms, rights, and responsibilities of shareholders
Require board approval for subleasing
Decisions are made at shareholder meetings
Co-ops and Trusts: A Complex Relationship
A trust is a fiduciary arrangement allowing a third party to hold assets on behalf of a beneficiary.
When it comes to co-ops and trusts:
Each co-op apartment can typically only be owned by one person.
Transferring co-op shares and proprietary lease to a trust requires board approval.
Some boards allow apartment transfers to trusts, while others don't.
Estate Planning for Co-op Owners
If parents who own a co-op pass away:
Their child would typically have to go through probate.
This can be problematic if bank accounts freeze, as co-ops rely on regular maintenance payments.
To avoid these issues, consider putting the co-op in a trust.
Benefits of placing a co-op in a trust:
- Smoother asset transfer to beneficiaries
- Maintains regular maintenance payments even after an owner's death
- Clarifies how and when assets pass to beneficiaries
Governing Documents for Co-ops
Co-ops are governed by several important documents:
1. Bylaws: The most crucial document, outlining regulations and procedures
2. Articles of incorporation: Along with bylaws, these form the foundational documents
3. Policy Manual: Clarifies expectations for board, members, and staff
4. Terms of Reference: Outlines committee composition and duties
Changing co-op bylaws requires a board meeting, vote, and usually a majority approval. Amended bylaws must be filed with the appropriate state agency if required.
