Postponement and Reservation: What's the Difference and How to Avoid Losing Protection During Mobilization?

Postponement and Reservation: What's the Difference and How to Avoid Losing Protection During Mobilization?

The mobilization situation in Ukraine has changed: new legislation, electronic registers, and stricter control have affected both employees and employers. In this context, people often ask: “Have you been reserved?” or “I have a postponement, I’m safe.” But here’s the issue — postponement and reservation are not the same, and this confusion has already led to hundreds of mobilizations, fines, and loss of legal protection.

The law firm “Case Lviv” explains the difference between these mechanisms, who has the right to what, and how to avoid critical mistakes.

Postponement — personal protection

Postponement is an individual right granted to a person based on legal grounds. Its goal is to temporarily exempt someone from mobilization, according to Article 23 of the Law of Ukraine “On Mobilization Preparation and Mobilization.”

The most common grounds include:

• Caring for a person with a disability

• Being a single parent

• Having three or more children

• Being a full-time or dual-form student

• Being temporarily unfit for service

• Having other individual grounds not covered by reservation

To get a postponement, a person applies to the military enlistment office (TCC) with an application and supporting documents. If approved, the postponement lasts until martial law ends. As of 2024, some postponements are automatically extended if the grounds remain valid.

Reservation — employer’s initiative

Reservation is a different mechanism. It is not an individual right of the employee but a tool used by critical enterprises. The employer applies through the “Diia” portal and includes a list of employees, their positions, and justification.

Who can reserve employees?

• State authorities

• Critical infrastructure companies

• Strategic enterprises

• Defense industries

• Organizations recognized as critical by the Cabinet of Ministers

If approved, the reservation is recorded in the state register and is valid for up to 12 months. Not everyone can be reserved — the employee must be officially employed, on military records, and meet age and legal criteria.

Key differences

If a person already has a postponement, they can’t be reserved — and vice versa.

Common mistakes

• Relying on verbal promises that you’ve been “reserved”

• Applying for both mechanisms at once — and being denied both

• Employers trying to reserve workers without having the legal right

• People with valid postponements missing deadlines or failing to update their documents

All these mistakes come from a lack of legal guidance and proper document review.

Who should act first?

Each person is responsible for their own legal status.
If you’re an employee — check your eligibility for postponement and apply.
If not — ask if your company has the right to reserve you.
If you’re an employer — check whether you meet the criteria for critical status and follow official procedures.
