A Haryana Patwari maintains land records for their assigned circle including jamabandi (updated every 4 years), Girdawari register (biannual crop inspection), and khasra girdawari. They record changes in land ownership through mutation (intkal), prepare reports on agricultural production, and assist in natural calamity damage assessment for compensation. Haryana Patwaris use the Jamabandi Portal (jamabandi.nic.in) for digital record maintenance and issue nakal (certified copies) of land records to citizens. They work under Kanungos and report to the Tehsildar for revenue administration.

The Haryana Patwari exam syllabus includes General Knowledge of Haryana (history, geography, culture, polity, economy, schemes, current events), Hindi (grammar, vocabulary, comprehension), Mathematics (arithmetic, algebra, geometry, mensuration), Revenue Laws & Land Records (Punjab Land Revenue Act, Haryana land reforms, mutation procedures, jamabandi formats), and Reasoning (logical, verbal, non-verbal). The Punjab Land Revenue Act 1887 is applicable to Haryana and is frequently tested. Questions on Haryana's agricultural economy, irrigation systems, and rural development schemes are also included.

A Haryana Patwari receives a basic pay in the pay matrix corresponding to a Grade Pay of Rs. 2,400, with gross monthly salary of approximately Rs. 22,000–28,000 including DA, HRA, and field allowance. The in-hand salary is approximately Rs. 19,000–25,000 per month. Special field duty allowance is provided for Girdawari surveys and village visits. Career progression includes promotion to Kanungo, Naib Tehsildar, and Tehsildar levels through departmental examinations and seniority.

The Punjab Land Revenue Act 1887 governs land revenue administration in Haryana (as it was carved out of Punjab in 1966 and retained the same laws). It defines the powers of revenue officers, procedures for assessment and collection of land revenue, mutation of land records, and settlement operations. The Act provides for courts of revenue officers at different levels and outlines rights and liabilities of landowners. Since Haryana Patwaris operate under this law daily, the exam tests knowledge of key sections including those on record of rights, partition of estates, and correction of errors.

There is no restriction on the number of attempts for Haryana Patwari exam as long as the candidate is within the prescribed age limit of 17-42 years. However, the relaxation in upper age limit for reserved categories follows Haryana government norms — SC/BC candidates get 5 years relaxation, and ex-servicemen get relaxation as per policy. Candidates may apply as many times as vacancies are notified until they exceed the age limit. It is advisable to prepare thoroughly before each attempt to maximize the chance of selection.
