Short answer — for timely, reliable life-claim payments in Sri Lanka the companies most frequently highlighted (as of recent reporting) are Softlogic Life, Sri Lanka Insurance (state-owned), Union Assurance and Ceylinco Life. Each has strengths:

• Softlogic Life — repeatedly cited for fastest digital claim processing (one-day / automated/AI workflows) and large paid-claim volumes; good for quick settlements and digitally submitted claims. (softlogiclife.lk)
• Sri Lanka Insurance (SLIC) — the largest life insurer with very large life-fund and high total claim/bonus payouts; strong balance-sheet and long track record of paying large volumes of claims. Good if you prioritise financial strength and long history. (ceylontoday.lk)
• Union Assurance — emphasises digital customer experience and reports very high one‑day health-claim settlement ratios; good for customers who want simple digital claim filing and responsive service. (economynext.com)
• Ceylinco Life — frequently awarded “best life insurer” and known for consistent service and claims capability; strong brand reputation. (ceylincolife.com)

How to pick the best for you

• Look for published claim-settlement metrics (one‑day/one‑month ratios) and recent paid‑claims or benefits numbers. Softlogic and Union publish fast‑settlement stats; SLIC publishes claim/bonus volumes. (softlogiclife.lk)
• Check solvency / financial strength and latest IRCSL (Insurance Regulatory Commission of Sri Lanka) reports. (Regulatory/surplus position impacts ability to pay large claims.)
• Read policy contract wording for claim exclusions, documentation required, contestability and time limits — a faster-settling insurer still needs complete documentation to pay quickly.
• If you already have a policy, consider insurer track record for the specific claim type (death benefit vs hospitalisation vs critical illness).

If you’d like, I can:

• look up the latest IRCSL claim-settlement or solvency reports and compare current published one‑day / settlement ratios for these companies (I can fetch 2024–2025 figures), or
• help you compare two specific insurers or one particular policy wording.
