Sale of a share by a co-owner

Deadline calculator for notice of sale of a share

For shares in Lviv apart­ments and family homes in the region, co-owners often live at dif­fer­ent ad­dress­es or abroad. Before selling to a third party, it is there­fore im­por­tant to have sep­a­rate proof that each re­cip­i­ent re­ceived notice. The cal­cu­la­tor uses the latest proven date and stops sce­nar­ios that cannot be re­solved by simply adding a time period.

Check the route and earliest sale date

Enter the latest con­firmed date when all co-owners re­ceived the same notice. If there are mul­ti­ple re­cip­i­ents, use the latest proven date.

What ownership regime is stated in the documents?
What action is planned?
Who is the share intended to be sold to?
What share is being sold?

Not the date of the letter or its dis­patch. For several co-owners, enter the latest con­firmed date of actual receipt.

Has actual receipt been confirmed for everyone?
Is receipt disputed?
Have the sale terms remained the same?
Has the sale to a third party already taken place?
Is there a written refusal from all co-owners?
Apply the cautious Saturday/Sunday adjustment?

The period is tied to receipt of the notice. The sending date without proof of actual receipt does not provide a re­li­able start date.

What exactly the calculator calculates

Article 362 of the Civil Code of Ukraine gives a co-owner the pre-emption right to buy a share at the an­nounced price and on other equal terms. The seller must notify the other co-owners in writing. If they do not ex­er­cise the right, the period from receipt of notice is one month for real estate and ten days for movable prop­er­ty.

Ar­ti­cles 253–255 set the cal­en­dar frame­work: a period starts the next day, a period stated in months ends on the cor­re­spond­ing date, or on the last day of the month if that date does not exist. Moving the final day depends on whether that day is non-working in the spe­cif­ic sit­u­a­tion, so the cal­cu­la­tor applies only an ex­plic­it Sat­ur­day/Sunday ad­just­ment.

A sep­a­rate step-by-step guide on selling a co-owned share sup­ple­ments the prac­ti­cal pro­ce­dure for prepar­ing a notice, ev­i­dence, and agree­ment.

Calculation methodology

Pre­lim­i­nary cal­en­dar method­ol­o­gy

  1. We check that this is a sale of a spe­cif­ic share in jointly owned prop­er­ty, not another prop­er­ty or trans­ac­tion regime.

  2. Already com­plet­ed sales, changed terms, dis­put­ed or un­proven receipt, and dates outside the current scope are ex­clud­ed.

  3. For all re­cip­i­ents, use the latest proven date on which the same notice was re­ceived.

  4. Add one cal­en­dar month for real estate or ten cal­en­dar days for movable prop­er­ty.

  5. Only when ex­plic­it­ly se­lect­ed: a Sat­ur­day or Sunday is con­di­tion­al­ly moved to Monday; the ear­li­est sale date is shown start­ing the fol­low­ing day.

Example

Example of an apartment share in Lviv

The owner of a 1/2 share in an apart­ment in Sykhiv is ne­go­ti­at­ing with an outside buyer. The other co-owner is outside Lviv and is con­firmed to have re­ceived the full notice on 31 January 2026.

  • Common frac­tion­al own­er­ship and sale of real estate
  • Con­firmed receipt: 31.01.2026
  • The price, payment pro­ce­dure, and other terms have not changed
  • There is no express refusal by all co-owners

The period starts on 1 Feb­ru­ary. Since Feb­ru­ary has no 31st day, the nominal one-month period ends on 28 Feb­ru­ary, and the cal­cu­la­tor will show 1 March 2026 as the ear­li­est sale date.

The example does not prove proper notice or review no­tar­i­al doc­u­ments. If the end date falls on a weekend, the rules for per­form­ing the action must be checked sep­a­rate­ly.

What to prepare before selling a share

  • Title doc­u­ments and current in­for­ma­tion about reg­is­tered shares and en­cum­brances.
  • Draft written notice stating the exact price, payment method and dead­line, and other terms.
  • Sep­a­rate ev­i­dence of the con­tents and actual receipt for each co-owner.
  • Written re­fusals from co-owners if the sale is planned before the full period ends.
  • Draft agree­ment with terms no more fa­vor­able to an outside buyer than those no­ti­fied to the co-owners.
  • Doc­u­ments about mar­riage, chil­dren’s rights, use of the prop­er­ty, arrests, mort­gages, or other en­cum­brances, if they relate to the asset.

Frequently asked questions

From what date should the month or ten days be counted?

From the co-owner’s actual receipt of written notice. If there are several ad­dressees, use the latest proven receipt date for a cau­tious shared cal­en­dar.

Is it enough to state only the value of the share?

No. Article 362 re­quires dis­clo­sure of the price and other sale terms. The method and timing of payment, any de­fer­ral, and other ma­te­r­i­al terms must match the in­tend­ed trans­ac­tion.

What does a co-owner’s written refusal change?

An express refusal may remove the need to wait out the full period for that co-owner. If there are several co-owners, proof of refusal from each is re­quired; the cal­cu­la­tor shows a cau­tious date after the last refusal.

Should the end date be extended if it falls on a Sunday?

Article 254 links a shift to a non-working day. The cal­cu­la­tor does not know a par­tic­u­lar notary’s or in­sti­tu­tion’s sched­ule, so it moves the date only for Sat­ur­day or Sunday and only if you ex­plic­it­ly select that option.

What to do if the price was reduced after notice?

Do not au­to­mat­i­cal­ly rely on the old cal­en­dar. The co-owner must have been given an op­por­tu­ni­ty to buy on equal terms; changed terms should be as­sessed, and it is usually safer to notify them again.

Does the tool calculate the claim period after a sale has already taken place?

No. The one-year lim­i­ta­tion period for a claim to have the buyer’s rights and oblig­a­tions trans­ferred depends on a sep­a­rate base date and cir­cum­stances. This cal­cu­la­tor de­lib­er­ate­ly does not de­ter­mine it.
