How it applies
Common Examples

Corporate Filing Without Delay
Eastern Electric filed articles of incorporation on March 15 without specifying any later date. The secretary of state accepted the filing that same day. Corporate existence therefore began immediately, allowing the company to enter binding contracts the following week without personal liability for the organizers.
Support Order Modification
Emmett Egan obtained a child-support order in State A. After State B modified the order, State A retained authority to award relief for any violations that occurred before the modification took effect. The court therefore calculated arrears using the original order up to the modification date.

Echo Systems created an irrevocable trust directing distributions for a beneficiary's health and education. The trustee applied the ascertainable-standard definition that was in effect on the date the trust code became operative. Later amendments to the Internal Revenue Code did not alter the standard used for this trust.
Power of Appointment Timing
Edward Everett executed a will attempting to grant his daughter a power of appointment over trust property. The daughter died two weeks before the will was admitted to probate. Because she died before the document's effective date, no power of appointment was ever created.
Ordinance Effective Date
The City of Hialeah passed an ordinance regulating animal sacrifice. The ordinance stated it would become effective upon signing by the mayor. Once signed, the provisions applied immediately to pending permit applications without any further grace period.

Legislative Effective Date
A state statute reapportioning legislative districts was enacted on June 1. The law specified that it would take effect on the first day of the next regular legislative session. Until that session began, the prior district lines remained in force for all elections.

Common questions
Frequently Asked
3
How does a delayed effective date affect corporate formation under the Model Business Corporation Act?+
Corporate existence begins on the filing date unless the articles expressly specify a later date. The delayed date postpones only the start of corporate existence and does not affect the validity of the filing itself.
Supporting sources
Can a support-order modification apply retroactively to pre-modification violations?+
Yes. The tribunal that issued the original order may still enforce it as to arrears and interest that accrued before the modification and may award appropriate relief for violations occurring before the effective date of the modification.
Supporting sources
What happens if the donee of a power of appointment dies before the creating document becomes effective?+
No power is created. Any attempted exercise of the power is ineffective because the document conferring the power never took effect during the donee's lifetime.
