The major objective of allowances under the Social Insurance Fund is to provide the means of support to the insured persons who are unable to continue their economic activity for natural reasons (i.e. after they reach the age stipulated in the relevant regulations) or because of being incapable of work. This is why the right to the pension depends not only on the certified incapacity for work and proven insurance period, comprising contributory and non-contributory periods. It is equally important when the person applying for the pension became incapable of work. Pursuant to the provisions of the Act of 17 December 1998 on Old-Age and Disability Pensions from the Social Insurance Fund (Journal of Laws of 2018, item 1270 as amended), a prerequisite for acquiring the right to the pension is the emergence of the incapacity for work (total or partial) in the insurance period or no later than 18 months after its end.
