Substitution Clauses in a POA: Letting Your Attorney Delegate — or Not

Welcome back to the POA's desk.

In the last episode we covered multiple attorneys and joint authority. In this episode we cover substitution clauses — the provision that allows an attorney to delegate their authority to someone else, and why this is one of the most overlooked aspects of POA drafting.

What a substitution clause is

A substitution clause is a specific power written into a POA that allows the named attorney to appoint another person to act in their place. With a substitution clause, the attorney can pass their authority on, in whole or in part. Without a substitution clause, the attorney's authority is personal — only they can act under the POA, and they cannot delegate it.

This sounds technical but the practical implications are significant. A POA without a substitution clause locks the principal into a single chain of representation. If the named attorney becomes unavailable — through illness, travel, or simply being too busy — there is no fallback. The principal must issue a new POA, which may take weeks if they are overseas.

A POA with a substitution clause provides flexibility. If the named attorney cannot act, they can appoint a substitute to take their place. The principal does not need to issue a new POA. The transaction can proceed.

But substitution clauses are not universally good. They also expand the chain of authority. Once a substitute is appointed, that substitute is acting under the principal's POA, even though the principal may never have heard of them. This can be a feature or a risk depending on the situation.

When substitution clauses make sense

Long-running POAs where the attorney may not always be available. A Property Management POA valid for five years should probably allow substitution, because the named attorney may travel, fall ill, or relocate during that time.

Time-sensitive transactions where the attorney's continued availability is uncertain. A Property Sale POA where the attorney may not be in Dubai when the trustee appointment is finally scheduled.

Situations involving overseas principals where re-issuing a POA is slow and expensive. Substitution allows the attorney to appoint a UAE-based substitute without the principal needing to start the consular chain again.

When substitution clauses do not make sense

Single-transaction POAs where the principal wants tight control over who can act. A specific Property Sale POA with a known timeline and a known attorney does not need substitution.

Sensitive matters where the principal's trust in the attorney does not extend to whoever the attorney might appoint. If the principal trusts X but does not necessarily trust whoever X might delegate to, the substitution clause should be omitted.

POAs involving significant financial authority where the principal wants the attorney's personal accountability. Substitution dilutes accountability because the substitute is appointed by the attorney, not by the principal.

The wording matters

The wording of a substitution clause matters. A broad clause says "the attorney may appoint a substitute to act in their place with the same powers." This is the most flexible. A narrower clause says "the attorney may appoint a substitute only with the principal's prior written consent." This preserves principal control but may be impractical if the principal is hard to reach. A specific clause says "the attorney may appoint substitute X if needed." This pre-identifies the substitute and limits the chain.

Two scenarios

A practical scenario. A property owner in Singapore issues a Property Sale POA to a friend in Dubai. The friend is reliable but travels frequently. The POA includes a substitution clause allowing the friend to appoint an alternate if needed. When the friend is travelling at the time of the trustee appointment, they appoint a colleague as substitute. The colleague attends the trustee with the substitution document and the original POA. The transaction completes without the principal needing to be involved.

Another scenario. An elderly parent issues a Property Management POA to their adult child. The child's life is settled and they do not expect to need substitution. The POA omits the substitution clause. When the child later needs to travel for an extended period, they cannot delegate. The parent must issue a new POA naming a different attorney. This is the cost of omitting the clause.

Common mistakes

A common mistake we see. Principals do not think about substitution at all. They assume the named attorney will always be available, or they assume substitution is automatic. Neither is correct. Substitution must be explicitly granted in the POA.

Another common mistake. Principals include a broad substitution clause without thinking through who the attorney might delegate to. The substitution clause grants the attorney authority to appoint anyone, which means the principal has no control over the substitute's identity. If this matters, the clause should be narrowed.

At POAS we discuss substitution as part of the drafting process. We explain when it is helpful, when it adds risk, and what wording reflects the principal's preferences. The clause is included or omitted based on that conversation, not by default.

In Episode 22 we cover POAs for minors and dependents. The specific requirements when the principal is or has a child involved in the POA.
