A key feature of a company is its name (company name). It has to be chosen at the time of the establishment of the company and must be unique., it must not coincide with the name of another company already entered in the Commercial Register.
How do I reserve a company name?
The reservation of a name (company name) is a service provided by the Registry Agency, which provides temporary protection of the chosen name . During the reserved period of time no other person may register a company under the same name.
The company name is determined freely by the trader and it must not be misleading or violate public order and morality, nor infringe on the rights of another trademark or company. It is mandatory that the name is written in Bulgarian language, while in addition it’s also permitted to be written in another language.
| Important to know | |
 | Prior to the filling-in of the application at the website of the Commercial Register you can check whether the name chosen is already selected by another trader. |
Reservation of a name is made by virtue of filing a standard form application[1] with the Commercial Register. Application is form “D1” (in Bulgarian: Д1) and it may be filed on site at the registration desk of the Registry Agency or online via the website of the Commercial Register and the Register of Non-Profit Legal Entities.
A qualified electronic signature held by the applicant or a person authorised by the applicant is required to file an online application [2].
What is the period of time over which a name is reserved?
A name is reserved for the applicant over a period of 6 months. During the time only the applicant may register a company under that name.
When the 6-month term expires, there is no obstacle to file a new application and to reserve the name for a new period of 6 months.
Why should you reserve a company name?
It makes sense to reserve a name when the entrepreneur/future partners have selected a vacant name, but are not ready to register a company yet.
There is no legal obstacle to reserve more than one name. Their reservation does not give rise to an obligation to register a company.
| Fee | The filing of the application online is recommended as it saves time and effort and the fee due to the Registry Agency is fifty percent lower. In case of filing the application to reserve a name on site the fee amounts to BGN 40, while electronic reservation costs BGN 20. |
